To all whom it may concer/rr: l

Be it known that I, JOHN WOOD, a citizen of the United States, residing at Grrand Island, in the county of Hall and State of Nebraska, have invented certain new and useful Im rovements in Attachments for Self-Prope ed Vehicles; and Ido hereby declare the following to be a full, clear, and eX- act descri tion ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in attachments for self-propelled vehicles.

The object of the invention isv to ,provide means for breaking the interlock between the operating lever for throwing the' transmis` sion gear into and out of operative relation.

Specically the invention consists in lproviding an operating lever so associated with the connecting means between it and the transmission gear that said lever may be locked to said connecting means and mov-- able therewith, or unlockedfrom said connecting means and movable independently thereof, in which latter position the trans-f mlssion gear may not be operated by an intermeddler.A j j While the invention is not 'restricted to the exact details as shown and described, still for the/*purpose of disclosure reference is had to thev accompanying "drawings illustrating a practical embodiment of the invention, in which drawings like numerals designate thel same parts in the two views, and in Which- Figure 1 is afside elevation of an operating lever for a self-propelled vehicle showing' my invention apphed, and showing in section the connectmg means or shaft between' the o erating lever and transmission gear, and

1g. 2 is a front elevation of the same.

1 designates the usual operating lever provided with the paw12, pawl rod 3 and grlp 4, the pawl 2 coperating with a suitable rack bar 5. This operating lever is enlarged at its lower end, as at 6, and receives the rock 'shaft 7 forminga'connection between said lever and the transmission gear of the vehicle. The leveris so associated with said shaft that it may freelyfpivot thereon when unlocked therefrom, and while not shown, suitable keying means may be provided 4to revent the lever from side play on the shaft, butallowing it to freely rotate thereon when unlocked. The shaft 7 is provided with a slot 8, which slot coperates with a locking member 9 carried by a rod 10 mounted on Specification of LettersxPatent. Application filed February 3, 1908.

the side of the lever 1. This rod 10 may be spring 11 coiled around said rod and disposed -etween the shoulder 12 on said rod and the guidindg support d13 on the lever 1'.

14 the lever 1, and- 15 designates a lateral projection apertured and adapted to coperate with a similarly apertured ateral projection 16 carried by the upper end of the rod 10,

same directiony andthe apertures therein being adapted to aline when the rod 10"is elevated, in .which position any suitable lockinmeans, such as a padlock 17, may be asse through said apertures to hold the ro 10 1n itsvupper positlon.

l necessarily be located adjacent the lever`1, for if desired, for instance, the lever maybe provided with a longitudinal slot rece1v1ng the rod 1, or the lever may be longltudlnally bored and provided with a slot at the upper end of the bore to allow the lateral projection 16'to operatetherein.

The operation of the device 1s. apparent, 1t

9 is in the elevated position shown with the padlock in position, the lever 1, if moved at all, will move independently of the rod 7, and hence will not affect the transmission gear. 'On the other hand, when the rod 10 is released and the locking member 9 is forced down into the recess 8 the rod 7 becomes interlocked with the lever and will be operated thereby upon the movement of the latter to throw the transmission mechanism in or out lof operative osition. lThus it will be seen that I provi e asimplel means for effectively `preventing an intermeddlef moving the veicle through the use of its own power, avoiding theft or other misuse.
